My invention rela-tes to adjustable seats, particularly adapted,although not necessaj rily, tor use in automobiles ot the coach or titldit

coup type. l

llt is a purpose ot my invention to provide a vehicle lseat havingrelatively simple, inexpensive and durable means by which the seat canbe quickly adjusted horizontally toward or away trom the steering wheelto accommodate drivers ot diderent leg; lengths;

vertically to any desired height within cer tain limits; and a seat inwhich the seat portion as well as the back portion can be tilted to anydesired inclination to suit the requirements ot a particular driver, allot' the recited adjustments being embodied in a structurewhich ishingedly mounted to permit the torward folding ot the seat when desired.

l will describe only one torni ot adjustable vehicle seat embodying myinvention and will point out the novel features thereot' in claims.

ln the accompanying drawings,

Figure 1 is a view showing,r in side elevation and partly in section onetorno ot ad- "l justable vehicle Seat embodying my invention in appliedposition to the door ot a motor vehicle;

Figure 2'is a vertical sectional view talren on the line 2--2 ot Figure1;

Figure 3 isa horizontal sectional view talren on the line 3-3 ot Figurel.

Reterring specifically to the drawings, 1n ywlnich similar referencecharacters referto similar parts in each ot the views, my 1n` f"vention, in its present embodiment, com-4 prises a base trame made up ota pair ot' i. `identical barsor plates 15 lia-ving" slots 16 extendinglongitudinally thereof tor the reception ot bolts 17, which =latter arevsecured to the door 18 ot a motor. vehicle and capable ot manipulationto permit longitudinal adjustment ot the bars and the-securing :ot thebars in. any longitudinally adjusted position within the limits delinedby theslots le. its shown in Figure 1, the torward ends of the bars 15are constructed to provide hinges 19 `tor hingedly mounting the torwardends ot a pair ot metal strips 20, the latter being riveted or otherwisesecured to the base -tlanges 21 ot a pair ot plates 22, all as clearlyshown in Figure 2. 'llhese plates 22 constitute. the lower portion ot asupporting trame, the upper portion et the supporting trame being madeup ot' a pair 'ot plates 23 having top danges 2t which are permanentlysecured to strips 25 termed ot' wood or other suitable material andconstituting part ot' a seat trame.

As shown in Figures 2 and 8, the seat trame comprises a rectangularstrip ot' metal or t@ other suitable material 26 in which is secured abottom'27 tor supporting a seat cushion 28. flhe strips 25 are securedcontiguous 'to the side portions ot the trame 26, and becured within thetrames, as clearly shown. As shown in Figure 2, the upper edges ot thebars 29 areplipped as indicated at 30, in order to provide between thebars and strips slots `tween such portions metallic bars 29 are se- @5 i31 wherein the upper portions ot the plates l@ 22 are received.

As shown in Figures 1 and 2, the plates 22 are provided at intervalsalong' the. length thereof with vertical slots 32, while the plates 23are each tormed with 'a pair ot arcuate l5 slots 33 at pointscorresponding to the two end-most slots ot the plates 22. a'll`heseveral slot-s of both plates are adapted to receive bolts 311 providedwith headed nuts 35 and washers 36, the bolts and nuts bcinfr assot@ciated with the plates in the manner clearly shown in Figure 2, and theconfronting sides ofthe washers and bolt heads serrated for engagementwith t-he serrated outer sides ot the plates 22 and 23 whereby the boltsand ttt washers can be operated to ed'ectively secure the plates ot thesupporting' trame in adjusted position. The vertical slots 32 permitvertical adjust-nient ot the upper plates 23 on the lower plates 22, andin this manner the seat trame is capable ot being' adjusted verticallyto vary its horizontal position. The arcuate slots 33 permit tiltingadjustment of the plates 23 on the plates 22 so that the seat trame canbe tilted upwardly or'downwardlyT tta to vary the inclination of theseat cushion 28.

its clearly illustrated in Figure l, the side portions of the trame 26adjacent the rear ends thereof are provided with superposed slots 37 toreceive bolts 38 carried by arms toa 39. The lower ends ot the arms aretormedl with arcuate slots t0 in which the correspondx ing bolts 38work, while the upper ends ot the arms are' hingedly connected to a'trarne t1 :tor a seat back d2; rlhrougrh the medium ot the slots 37 andthe bolts 38, the arms 39 are capable of. horizontal adj ustrnentforwardly or rearwardly with respect to the seat trarne so as t-o rarthe position ot the seat bach 4t2 torware y or'rearwardly titl withrespect to the seat cushion 28.
